Whether diet or lifestyle, one must stay healthy to avoid diseases, disorders, and any illness. However, there are several disorders associated with the human heart if it doesn’t function properly or if it is not in a good state.


The difference between AFIB, or atrial fibrillation, and CHF, or Congestive heart failure, is the causes of the respective disorders. Atrial fibrillation is caused due to the occurrence of problems in the heart valves. On the other hand, congestive heart failure is caused due to a heart attack or any other disease associated with the coronary artery.

It is caused due to several reasons, but mostly it is caused due to high blood pressure and problems associated with the heart valves. It can be treated and cured by medication. There are other treatment options as well.

There are several diagnosis options by which one can understand if they have CHF or not. However, ECG and/ or a chest X-ray are some of the common diagnosis options.

Full formsAtrial fibrillation Congestive heart failure
Meaning/ DefinitionThe disorder in which the atria present in the human heart lacks rhythm or beats irregularly is known as atrial fibrillation or AFIB.The disorder in which the pumping of the heart is not done well and due to which the fluids in the body are amassed is known as congestive heart failure or CHF.
Risk factorsPeople aged 60 years and above are more likely to have this disorder, as people with blood pressure issues, people with coronary artery disease, etc.People who have a family history of congestive heart failure, people who are diabetic, people who have coronary artery disease, etc.
What happensThe rhythm of the atria is irregular.The fluids get collected due to the improper pumping of the heart.
SymptomsShortening of breath, difficulty in doing activities like exercising, feeling light in the head, etc.Swelling is observed in the ankles, fatigue, and difficulty in breathing.

What is AFIB?

AFIB, or Atrial fibrillation, is a heart disorder that, when it occurs, causes irregularities in the rhythm of the atrial. It is one of the most severe heart disorders, and it is most likely to be diagnosed in people who are sixty years or above.

Other than that, it can also be caused due to hyperthyroidism, a condition where the thyroid hormone from the gland present in the neck is produced in huge amount and thereby increase the body’s metabolism.

If a person is feeling difficulty in breathing, light in the head, fatigued, face difficulty in activities like exercising, feels weakness in the body, or faints, then they must visit a doctor as these are some of the symptoms that are observed in a human body whenever he or she has atrial fibrillation.

However, atrial fibrillation can be treated and cured. One of the most effective treatments doctors follow or prescribe is AV node ablation.

What is CHF?

CHF, or congestive heart failure, is a disorder related to the human heart which occurs when the heart doesn’t pump properly, resulting in the collection of fluids in the body.

People with blood pressure issues, people with a family history of congestive heart failure, people with problems associated with heart valves, and people with coronary heart disease or cardiomyopathy are more likely to get diagnosed with congestive heart failure.

If a person’s left ventricle of the heart is affected, then he or she can feel extremely weak and tired, can face difficulty in breathing, and the cardio output is also reduced.

A patient can be cured by introducing some changes in his or her diet and lifestyle and by following medications. Other than that, the treatment options may vary depending on the severity of the disorder.

Main Differences Between AFIB and CHF

  1. One can get congestive heart failure if one has a family history of it. On the other hand, one can not get atrial fibrillation if one has a family history of it.
  2. Treatments to cure atrial fibrillation include AV node ablation. On the other hand, the treatments to cure congestive heart failure include a heart transplant if the severity is more, medications, and changes in dietary schedule and lifestyle in general.
